If not,
carefully change them to the correct values so you have your
whole amp working right. If this is too difficult for you - and it is
pretty hard to get that board out of there, desolder from a printed
circuit board, and refit parts without destroying traces, then get a
pro shop like ours to fix if your you.

this also points out a
really horrid "internet trick" that is totally wrong. You CAN NOT
remove one power tube of a two power tube amp to get half power.

both tubes are needed
in the Push Pull circuit. they "trade off" amplifying the signal
milli-second to milli-second. Half the wave form on one tube, the other
half on the other - taking one tube out clips off half the wave form
creating a horrible sounding crossover distortion, and leaves half the
output transformer running its signal into no load - this
will burn the output transformer up in short order, the bias supply,
the phase inverter and WILL NOT give half the power, more
like 1/10th the power until eventual failure of many parts.

Of course we offer
diagnosis and repair of this problem in our shop every day and can fix
if for you.Torres EngineeringTech Dept.
